Make Sure you have a PCI-E PCI Express SLOT on your MotherBoard

PCI-Express, the SiI 3132 offers full advanced SATA functionality normally limited to server-class systems, including 3 Gb/s SATA data transfer rates, Native Command Queuing, support for port multipliers with Frame Information Structure (FIS)-based switching and support for ATAPI commands, making it compatible with optical drives such as CD-ROMs and DVD+/-RWs. In addition, the ability to drive two-meter cables for external SATA drives enables a new class of high-speed storage for the PC market. The SiI 3132 offers advanced RAID capability through Silicon Image\'s SATARaid™ software RAID management utility, which comes bundled with the chip. The SiI 3132 supports RAID 0 and 1 when two drives are connected directly to the chip\'s two SATA ports. When multiple drives are connected to the SiI 3132 via a port multiplier such as Silicon Image\'s SiI 3726™, RAID 0, 1, 10 and 5 are supported.
